PASTRY Application filed July 10,

This invention relates to machines for cutting sheets 'of plasticmaterial into uniform fragments.

It is one object of the invention to provide a machine capable ofshearing sheets of chewing gum, confectionery, dough, etc., rolled to auniform, thickness into lozenges or diamonds of true and uniformrhomboidal shape. v

A further feature is in the provision of means. whereby such lozengesare formed with a double bevel'on each of. their several edges duringthe process of their manufacture and clean cut so that no ragged orrough surfaces appear. 1

Another aim is in the product-ion of a machine for accomplishing suchpurposes in the quantity production of goods, that is extremely simpleand eflicient and under the instant control of an operator.

These and other minor objects are attained by the novel construction andcombination of parts hereinafter described and shown in the accompanyingdrawings, forming a. material part of this disclosure, and in whichFigure 1 is a top plan view of an embodin'ient'of the inventionillustrating its application.

Figure 2 is a transverse sectional view taken on line 2-2 of Figure 1.

Figure 3 is a sectional View taken on line 33 of Figure 2.

Figure 1 is a rear end view of Figure 2.

Figure 5 is a. fragmentary transverse sectional view taken through theoblique cutting rolls.

Figure 6 is a fragmentary plan view of the dough sheet as it leaves themachine.

Figure 7 is an enlarged perspective view of one of the completedproducts.

The machine comprises a hollow bed frame 10 of rectangular profile, itslongitudinal members having flanges 11 and 12, respectively at the frontand rear, the latter being provided with an extension 13 at its forward,end and on the front side is an CUTTER.

1926. Serial No. 121,625.

open frame extension 14 these members to be supported by a bench or legsnot shown. Supported by the main bed 10 are a plurality of channelshaped spacers 15 carrying a flat level platform 16. of considerablearea, having at its rear edge a raised longitudinal rail 17. adapted toguide a sheet-18 of plastic material to be cut, this material havingbeen rolled to a uniform thickness by means well known in the trade.

Bolted to the bed flanges .11 and 12 are a pair of doublepillow blocks19, a similar pair of pillow blocks 20 being fixed on. the flange 11 andextension 13, in the same horizontal plane but at an oblique'angle tothe first blocks.

Each pillow block carries two bearings 21, 21 and 22, 22, respectivelyupper and lower, the lower being seatedin the bottoms of the blocks andthe upper supported by coiled compression springs; 23 disposed betweenthe bearings, which are slidably mounted and adjusted by screws 24: inthe pillow block caps 25,. v

- Revolubly mounted in the upper rear bearings 21 is a shaft 26, asimilar shaft 27 being in the lower bearings, these shafts extending atright angles across the bed.

Another pair of shafts 28 are mounted in the bearings 21 of the forwardangul'arly disposed blocks 20 as seen in Figure 1, oblique to the othershafts. v

Fixed on the shafts 26 and 27 are sleeves 29 and disposed-on the sleevesare fiat circular discs 30 having bevelled edges, these discs being heldin rigid uniform spaced relation by spacing collars 31, the lowercutting discs extending through appropriate slotted openings 32 in theplatfornr 16 to meet the peripheries of the upper discs in the manner ofpairs of circular. shears.

Fixed on they forward, angular shafts 28 are similar sleeves 83 carryinga series of longitudinal segments 34:, having between their adjacentfaces a series of straight, full length knives 35 provided withextending bevelled edges arranged in meeting relation,

at the center of the thickness of the sheet, the lower set of knivesoperating in a groove 36 in the platform 16.

This arrangement is best seen in Figure 5 and it will be noted that theperipheral surfaces of both series of segments 34 make contact with thematerial 18, as the shafts are revolved, tending to retain the sheetlevel and preventing its displacement by action of the cutters 35, whichare timed to rotate in proper relation with advancement of the sheet.

It will also be noted that the bevelled'edges of the cutters 30 producebevelled slits 18, as seen in Figure 3, while the bevelled edges of theknives 35, extending transversely across the slit sheet, producecorrespond ingly bevelled edgeslS, as seen in Figure 5.

Fixed on the outer ends of the shafts 26 and 27 are spur gears 37 and 38and the shafts 28 of the forward cutters are simi larly connected byspur gears 39.

Secured on the front end of the shaft 27 is a gear 40 and another likegear 41 is on the corresponding end of the lower angular shaft 28, bothgears 40 and 41 being driven by an intermediate pinion 42 fixed on ashaft 43 mounted in bearings 44 carried on the front extension 14 of thebed frame.

A pulley 45, driven by a belt 46, is rotat ably mounted on the shaft '43which can be driven by it upon engagement of a sliding friction clutchmember 46.

The clutch is actuated by a handled lever 47 extending conveniently foran operator and pivoted to a bracket 48 carried by the rear member-ofthe extension 14.

The operation of the machine is believed clearly apparent from theforegoing, taken in connection with the drawings and it will be obviousthat a sheet of suitable material may be cut to produce a multiplicityof parts, as seen in Figure 6, which upon separation will appear as inFigure 7, the angularity of each individual tablet being in con:lorinity with the angular relation of the front and rear cuttercarrying rolls.

The foregoing disclosure is to be regarded as descriptive andillustrative only, and not as restrictive or limitative of theinvention, of which obviously an embodiment may be constructed includingmany modifications without departing from the general scope hereinindicated and denoted in the appended claims.

Having thus described our invention, what we claim as new and desire tosecure by Letters Patent, is

l. A machine for cutting a plastic sheet into uniform rhomboidaltablets, comprising a platform over which the sheet is moved, a seriesof slitting cutters arranged above and below said platform the edges ofsaid cutters meeting in a plane midway the thickness of the sheet, theaxes of said cutters being at right angles to the path of the sheet, asecond series of cutters disposed in the same horizontal planes as thefirst cutters and at an oblique angle thereto, and means for rotatingall of said cutters simultaneously.
